@Baek Siyun I don't think he is proposing to her to stay togheter like a married couple, but like two persons that try to know each other for the first time and where he can pursue her because he loves her. She has the last decision after that. The fact that they are already married is a complications after all. I think she still can refuse to go out with him, he can't do anything against her will, it's exactly like Gladis did after all.
